Subject: What is the overall strategy to clear out the UCE? How to approach this?

It seems to me (admittedly a newbie) that nailing all the spam is not
going to be possible with Postfix. I understand that the RBL's are
not current enough to nail it all. It appears that by their nature, they
can't get ahead of the spammers: the spam has to be sent at least
once before it can appear in an RBL and plenty of it undoubtedly
never gets put into the RBL lists.

Requiring strict compliance with the appropriate RFC's would block
too much email that you want to get through.

Even if all email software strictly followed the RFC's, would that be
sufficient, with a properly configured Postfix, to block all the spam
(including reject_unknown_hostname, reject_non_fqdn_hostname,
etc.)?

It seems that we (email host admins) have to err on the side of
leniency toward the email sending masses and can't actually win this
war.

The only way I've seen to completely get on top of this is something
like Wieste has set up (a autoreply robot situation).

My goal here is to eventually create a email server for pay that is
completely spam-free but user friendly to my future subscribers and
their corespondents.. Is this going to be possible?

Your comments and direction would be greatly appreciated. I'm
trying to get the big picture here.

Cordially,
Scott.
